Part# 11-12858
MFR Model# 6430250-1


The model TI250 series Static Electrical Power Inverter is a lightweight power converter that translates a 20 to 36 VDC input to a 115 VAC output at 60 Hertz and provides 250 watts (VA) of power.

Supplies 250 watts of power to multiple cabin accessories, such as laptops, tablets and cell phones.

    Single engine turbo/piston prop, most small jets.
    (storm scope & boot type)
Highlighted features include short circuit protection, overload capability, low voltage shut-down, temperature monitoring, a self-resettable over-temperature disable, a remote on/off function, and a fault indication output.

The alternating current output is defined as a pure sine wave with less than 2% of total harmonic distortion for clean, noise-free, harmonic-free power to supply nearly any common commercial or consumer load rated for a nominal input of 115VAC. The TI250 series Inverter is FAA certified to TSO C73 and tested to rigorous environmental standards and levels of RTCA DO-160. The small size and light weight in conjunction with its installation flexibility (inside or outside the pressure vessel) make it an ideal choice for aircraft power needs while reducing the challenges associated with other similar products.

The TI250 has the same connector of legacy designs plus ground fault interrupter protection. The rugged extrusion that houses the unit is designed to help dissipate heat and provide mechanical strength against vibration or other possibilities of damage. The TI250 is engineered to run cooler and features a fanless design, which saves energy, reduces weight and allows flexible installation locations. At only 2.2 pounds, it is lighter and smaller than competing inverters. Additionally, the primary stage of the TI250 utilizes current mode control for increased reliability and safety.
